[0041] Example 1
[0042] A preparation method of an in-situ titanium-based composite composite laminated component, comprising the following steps:
[0043] A. Use wire cutting to process titanium-based composite materials and titanium alloy sheet samples with the same size and uniform thickness. The specific size is 50mm×50mm×4mm, and the titanium alloy sheet is Ti 6 Al 4 V titanium alloy, the in-situ reinforcements in titanium matrix composites include TiB and TiC, the volume content of reinforcements is 5%, and the volume content of TiB and TiC reinforcements is 1:1;
[0044] B. Clean the surface of each plate sample, and then use 200#, 400#, 600#, 800#, 1000#, 2000# metallographic sandpaper to polish the surface of the sample step by step, and then polish the polished sample plate Put it in acetone solution and use ultrasonic to clean it. After cleaning, it can be packed in a sealed bag to ensure the integrity of the surface of the sample;
[0045] C. Apply BN soluti...

[0053] Example 2
[0054] A preparation method of an in-situ titanium-based composite composite laminated component, comprising the following steps:
[0055] A. Wire cutting to cut titanium matrix composites (Ti 6 Al 4 V-TiB) and pure titanium plate, cut into 50mm × 50mm × 4mm samples, the volume content ratio of TiB reinforcement is 3%;
[0056] B. Clean the surface of titanium-based composite material and titanium alloy sheet, first use a grinder to make it smooth, and then use a relatively fine sandpaper to polish it to the surface roughness of 2000# sandpaper, and then put the polished sample plate into the Use ultrasonic cleaning in acetone solution, after cleaning, it can be packed in a sealed bag to ensure the integrity of the surface of the sample;
[0057] C. Apply BN solution on the upper and lower surfaces of the plates in contact with the pressure die, stick to each plate, and fix the four corners of the sample by spot welding, and then place them in a vacuum ...
